2 Claims.

This invention relates to dabbing brushes for combing machines and is herein illustrated as embodied in a multisection brush arranged to permit the relative displacement of the two parts to distribute the wear.

In combing machines which are provided with annular combs, the arrangement is such that these combs, of which there are at least two, move circumferentially along prescribed horizontal paths. The inner of the two paths is usually tangent to the outer path at some point, and the dabbing brush is reciprocated heightwise to push the wool, for example, onto the upright teeth of the combs near that point. Dabbing brushes are usually made longer than they are wide and are reciprocated vertically in a direction generally parallel to the teeth of the combs at a point adjacent to the point of tangency and covering that section of the combs where they separate. It is well understood that the wear of such brushes is rapid and that it is not well distributed since it takes place along a line, or lines, and is particularly in evidence at the so-called "heel or leaving end of the brush.

An object of the invention is to provide an improved dabbing brush wherein sections of the brush are removably and adustably attached to the head of the brush, thereby permitting ready distribution of'the wear without removing the brush from the machine.

An important feature of the invention resides in the provision of interlocking brush sections which, in the illustrated construction, are attached to the brush head by centrally-disposed bolts permitting the ready repositioning of the sections without removing the brush from the machine and at the same time insuring against movement of these sections during the reciprocatory action of the brush in the combing machine.

In the illustrated construction, one brush section is circular in form, and the other brush section is substantially rectangular with recessed sides to enable it to be brought close to the circular brush and to interlock with it.

These and other features of the invention will best be understood by reference to the accompanying specification taken in connection with the accompanying drawing, in which Fig. 1 is an angular view, looking down toward the head of the brush; while Fig. 2 is a plan view of an inverted brush.

Attached to the head Ill of the brush by centrally-disposed bolts H are brush sections l6 and I8 made up of bristle backs to which bristles, or

equivalent material, have been applied. The bristles may be secured in any well-understood fashion. That which is herein illustrated provides tufts of bristles wired in sockets in the bristle backs, but many other ways of making up the brush sections will be evident to those skilled in the art. The section I6 is circular in form and hence has convex peripheral portions, while the section i8 is rectangular in shape and is provided with peripheral recesses 20 enabling one side of this brush section to be brought into close relation to the convex periphery of section i6 and at the same time interlocked against rotation around its bolt [4. If wear takes place more rapidly near the heel 22 of the brush, then, the section l8 may be loosened from the body in and given a quarter turn to bring another portion of this section into the place of most active wear. Similarly, the section 16 may be turned upon its supporting bolt, as occasion requires, to distribute the wear occasioned by the path of the comb teeth extending longitudinally of the brush.

Such a brush will be supported in the combing machine in various ways according to the construction of the particular reciprocating member 24. In the illustrated construction, the foot 26 of that member is provided with a clamping bolt having a flat head 28 received in an undercut groove 30 formed in a body member 32 attached to the head ill of the brush by bolts 34 or screws 36 in awell-understoodfashion. This arrangement permits the brush to be removedfrom the reciprocating member 24 by loosening the clamping bolt and sliding the brush longitudinally until the bolt is freed from the groove 30. It will be understood that the illustrated arrangement, by distributing the wear over the various portions of the brush sections, enables the brush to'be used for a much longer period than is ordinarily the case and thus increases production by lessening the amount of time during which the machine must be shut down to remove and replace the brush. I

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. A dabbing brush, for a combing machine, comprising a head, a circular brush section thereon, and a removable, centrally-secured, auxiliary brush section on the head closely adjacent to the circular section and having its periphery provided with a plurality of segmental recesses whereby the auxiliary section'may be adjusted to bring one or another segmental recess into close 2*] 2,382,541 a x a, a

being symmetrical with respect to and adjustable proximity to the circular section to prevent the auxiliary section from turning during use.

2. A dabbing brush, for a. combing machine, comprising a head, bristle sections provided with bristle backs, bolts approximately centrally disposed in said bristle backs and arranged to hold the sections 'on the yhead with-their peripheries close to one -another, one of said sections having a convex peripheral portion and the other section about its bolt and having its periphery provided with a series, of recesses alternatively fitting the convex peripheral portion of the first section as the recessed section is adjusted to bring another recess adjacent to the convex section, thereby to hold the recessed section in thatposition;
